Purpose Built Imaging Informatics

At Radiologics, we focus on improving the efficiency and utility of imaging in clinical research. Clinical research is increasingly dependent on medical imaging. Indeed, over 8000 ongoing trials depend on one or more forms of imaging data – MRI, PET, CT, X-Ray, and an array of other modalities. Our software was built from the ground up to support imaging in these studies. We don’t cobble research workflows onto patient imaging “PACS” systems. We don’t add imaging as an afterthought to clinical forms “eCRF” systems. We do imaging informatics for clinical research.
